Please help me boyfriends to huge?

ok let me explain hes a ameature bodybuilder right now soon to be pro and im happy for him but he just takes up to much space like when we sit on a couch that can hold 4 with him on it you can only sit 2 or when we go in an elevator that can hold about 6 people with him in it you can barely fit a nother person inside hes just to big and i cant excactly ask him to loose some size it is his job after all but my question is should i break up with him over this i dont want to but hes just to big to go anywhere with hes 5'11 and 295 lbs btw and hes only 21
